Other People's Opinions

So quick back story, I have an amazing offer to go play at a junior college where I live the coach, the campus and it has a great engineering program(I want to be an engineer). But ever since I got the offer everybody has constantly been giving me their unwanted opinion and it's gotten so bad that I dread talking about my offer with anyone. This is supposed to be exciting and about ehat I want. But I can't even figure out what I want with everybody else's thoughts and opinions filling up my head. So, any advice on either a) how to tell them to respectfully shut up and let me figure out what I want? Or b) how to block out their opinions so I can figure out what I want?

Any advice would be appreciated!
